Is this trial a fit for you?
✓Likely a good fit
Ideal candidates for this study are patients experiencing their first episode of steroid-refractory GI-aGvHD with confirmed dysbiosis in their stool microbiota.
✕Probably not a fit
Patients with recurrent episodes of GI-aGvHD or those who have complications from previous colonoscopies may not benefit from this study.

What this trial studies
This clinical trial investigates the use of fecal microbiota transplantation (FMT) to treat patients suffering from gastrointestinal acute graft-versus-host disease (GI-aGvHD) following allogeneic hematopoietic stem cell transplantation (ASCT). The study focuses on patients with steroid-refractory GI-aGvHD who exhibit reduced bacterial diversity in their stool microbiota. FMT involves the infusion of healthy donor stool into the patient's gastrointestinal tract via colonoscopy, aiming to restore a healthy microbiome and alleviate symptoms of GI-aGvHD. The trial is designed to assess the efficacy and safety of this intervention in improving patient outcomes.
Why it matters
Potential benefit: If successful, this treatment could significantly improve the quality of life and survival rates for patients suffering from GI-aGvHD.
How similar studies have gone: Other studies have shown promising results with fecal microbiota transplantation in treating various gastrointestinal disorders, suggesting potential success for this approach in GI-aGvHD.
